The FA Cup third round tie between Crystal Palace and Brighton & Hove Albion will be the first competitive game in England in which video assistant referee (VAR) technology will be used.

But who will be the men in control of making the key decisions, if there any on-field issues that require the use of the VAR?

Andre Marriner will be the referee at the Amex Stadium and will make all the on-field decisions. But if there is any reason to refer to the VAR, Neil Swarbrick will be the video referee watching in London, who can direct Marriner to go and view a screen in between the two dugouts to analyse video reviews.
